Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991484, here are decompositions:

31 + 991453 = 991484
37 + 991447 = 991484
97 + 991387 = 991484
103 + 991381 = 991484
127 + 991357 = 991484
157 + 991327 = 991484
211 + 991273 = 991484
223 + 991261 = 991484

Showing the first eight; more decompositions exist.
